Abstract：TakingBayingolinMongolianAutonomousPrefectureinXinjangastheresearcharea，thisstudyexploresthespatiotempo raldistributioncharacteristicsofatmospericparticulatematermassconcentrationinareaswithfrequentstrongwinds.Byitegating groundmonitoring，remotesensing，and meteorological data，the studyreveals thespatiotemporaldistributionpattrnof PM2.5/PM10 .Research has shown thatthe time distribution is“high duringthe dayandlowat night”，with peaksoccuring between 9：00-18：00（PM2.5 （204 reaching 97.3 and PM10 reaching 173.2）.The concentration is highest in winter（ PM2.5 at 63.9and PM10 at 214.1）and lowest in summer.Thespatialdisrbutionisgativelyoelatedihvegetationoverge，decreasingwiticreasingaltiudeheonetatiois highestat thesouthern desert edge（ PM2，5 is 65.7， PM10 is 204.2）．Thevertical distributionhas the highest ground concentration PM2.5 （20 is 92.4， PM10 is 85.3）.The influence of wind speed is non-linear：the concentration is highestat low wind speeds of 0-1.5m/s ，and decreasesfirstandthenincreaseswithincreasingwindsped.Thisstudyrevealsthecomplexdynamicmechanismofparticulatematter pollution in areas with strong winds.
